Mailing in a payment to SNA? The lockbox address changes on October 12, 2021.  Please take note of the new address below to ensure that your payment is sent to the correct address.

SNA Lockbox Mailing Address: 

SNA Depository

PO Box 719297

Philadelphia, PA 19171-9297

Also, in light of the new USPS service changes, which may slow mail delivery, we encourage you to update your records to the new lockbox address.  SNA is working hard to ensure a smooth transition to the new lockbox address.  If your school district requires an updated W-9, vendor forms or if you have any questions, please contact us at
